README.md

Drone.io

Drone v1 is a Continuous Integration platform built on container technology with native Kubernetes support.

It is not recommended to upgrade from earlier (0.8.x) versions of Drone due to the large amount of breaking changes both in the product and in the helm charts.

TL;DR;

helm install stable/drone

Installing the Chart

To install the chart with the release name my-release:

helm install --name my-release stable/drone

note: The chart will not install the drone server until you have configured a source control option. If this is the case it will print out notes on how to configure it in place using helm upgrade.

An example (secrets redacted) working install of the chart using github as the source control provider:

helm install --name drone --namespace drone stable/drone

kubectl create secret generic drone-server-secrets \
      --namespace=cicd-drone \
      --from-literal=clientSecret="XXXXXXXXXXXXXXXXXXXXXXXX"

helm upgrade drone \
  --reuse-values --set 'service.type=LoadBalancer' \
  --set 'service.loadBalancerIP=2.1.60.3' --set 'sourceControl.provider=github' \
  --set 'sourceControl.github.clientID=XXXXXXXX' \
  --set 'sourceControl.secret=drone-server-secrets' --set 'server.host=drone.example.com' \
  stable/drone

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm delete --purge my-release

The command removes nearly all the Kubernetes components associated with the chart and deletes the release.
